Application filed September 25, 1920. Serial K; 412,667.

To all whom it may concern:

Be it known that we, THOMAS C. lfTEw- MAN and THEARON A. RICHARDS,citizens of the United States, residing at Rochester,

in the county of Monroe and State of New York, have invented certainImprovements in Vamp-Perforating Machines, of wh ch the followingdescription, in connection with the accompanyingdrawings, is a speck'fication, like reference characters on the drawings indicating likeparts in the several figures.

This invention relates to machines for operating upon sheet material andfor purposes of illustration is disclosed herein as embodied in a vampperforating machine, this application being a continuation in part ofour co-pending application Serial No. 295,349, filed May 7, 1919.-

In the manufacture of boots and shoes, it is usual to ornament certainparts of the upper by punching designs therein by means of a gangpunching machine. When it is desired so to use a pattern punch toornament some of these. parts, asthe toe portion of a vamp or wing tip,difiiculty isexperienced in presenting the work to.

the machine in the proper symmetrical manner, especially since inmachines commonly used for this work it is impossible to see that partof the stock to be operated upon after it has been placed in position tobe punched.

For purposes of of properly presenting a vamp to receive an ornamentalpunched pattern in its toe rtion 'will be considered in some detail,though it istobe understood that the invention is in no way limited inits applicability to the punching of Vamps. The toe portions of Vampsare not SYIII'. metrically cut onregular curves, and their outlinesdiffer according as they are rights or lefts and according to theirsize. It frequently happens that there are used ina dred. differentforms, the difierences being illustration, the problemsingle factorycamps havingseveral hun-.

longitudinal position of the pattern to be punched varies, being givenas a distance from the center of the throat of the vamp, and thisrenders still less feasible the use of edge gages contacting with thetoe portions of the vamps.

An object of the present invention, ac

cordingly, is to provide asatisfactory gage for positioning Vamps to beoperated 'upon and so constructed that its use shall be free from theseand other difliculties, and so that it shall be capable of satisfactoryuse by unskilled or unintelligent operatives. to present the work to theoperating parts of the machine with such speed. and certainty as willresult in a large output of acceptable pieces'of work with theperforating accurately placed. With this object in View a feature of theinvention comprises a gage arranged to engage the throats of Vamps to beperforated or otherwise orna-' mented and provided with novel adjustingmeans whereby the gage may be adjusted in two directions simultaneouslyso as to fit the throats of vamps of different sizes.

'Preferably the location of the gages with respect to the perforating.or other ornamenting means in accordance with the sizesof the Vamps isvaried .at the same time. As

illustrated the gage consists ofa pair ofmembers constructed to engagethe throats of Vamps and arranged for simultaneous adjustment in a preetermined ratio longitudinally of a vamp support and in oppositedirections transversely thereof, the ratio of the adjustments being suchthat as the gage members are moved longitudinally' a distance equal tothe difference in the desired distance of the perforation from thethroat of the vampin two different sizes, their position transverselywill be simultaneously varied just enough to con1- pensate for thedifference in the widths of the throat-sot the two Vamps. A scale may beprovided on a suitable part of the machine, numbered to correspond to asuitable range of sizes and in 00-0 erative relation to an index, thescale an index being .so related that as the gage is adjusted therelative positions of the index and scale indicate the size of vampcorresponding to the adjustment of the gage. Thus the operative mayeasily adjust the gage with pre- 1. c1s1on 1n accordance W1th the sizeof vam to be perforated.

. ture of the invention consists of means for varying the ratio of thelongitudinal to the transverse movement of the gage members. In theillustrated embodiment of the invention a scale and indicator areprovided in order thatthe operative may conveniently reproduce thedesired ratio'between these two movements; 7

When a vamp is to be provided with a line of perforations such as isknown as an imitation tip, orwitha medallion, it is frequentlyconsidered desirable to angle the perforation, that is, to position itwith the portion thereof on the outer side. of the shoe slightlyrearward of the portion on the inner side. A feature of the invention,ac cordingly, consists of means whereby the relative position of thegage and a gang punch by which the vamp is to be perforated may. eadjusted angularly about an axis perpendicular to the plane of the vampand die detached from the through the small angle necessary toaccomplish this pur ose.

With these an other objects ,in view, the invention will now bedescribed in connection with ,the accompanying drawings and pointed outin the claims.

The invention is applicable to the usualforms of punch presses and is shown in the present instance 1nconjunction with apress having a frame 25 carrying a main shaft 26driven by'means of a pulley 27 and operating a ram 28, the'latter beingprovided with a socket 29 and a set screw 30 for'securinga die block tothe ram. The present embodiment comprises. preferably, a die block orsupport 31 having a shank 32 (Fig. 9) and pivotally'secured to the lowerface of the block by means of a stud 33 (Fig. 10) is a die holder 34.The under face vof the latter carries at its end undercut guides 35which together form a wide dovetail groove or guide for receiving thecorrespondingly shaped die having an upper portion 36. Spaced,preferably, from the portion 36, by means of members 36, is a plate 37forming the face of the die from which projects a series of cutting orpunchingtools 38 arranged according to the design which it is desired.to' cut in the toe portion of the vamp.

justably connected-to the die block for the purposes explainedhereafter, the die holder being pivoted on the central stud 33, whichmovement is limited in either direction by.

the die holder by screws 42 on the rear of, the

latter, each having a head overlapping the portion 36 and by a clip 43engaging the forward side of the die portion 36 and secured by means ofa screw to the die holder.

The cutting tools 38 are preferably hollow punches, as indicated at 44,Fig. 17 extend- The die holder and die are together ading through plate37, for the escape of, the cuttingsand are disposed on the die to formthe desired design, such as an imitation tip or medallion with which thevamp is to be ornamented. One style of die is shown in Fig.15as having aline 45 of such punches, interrupted at its center. The cutting toolsare preferably provided with a stripping plate of any suitable form suchas that indicated at 48 (Figs. 15, 16 and 18 yieldably' secured to thedie as by means of a loose bearing on screws 49 fixed in the plate andinterposed compression springs 50 on the screws. If it is desired tomark orscore the vamp to serve as a adjacent to the perforations, orforother purposes, the stripper plate is preferably provided with proections 51 adapted to score the vamp, the resilient means supporting thestripper being sufiiciently stifi' to produce this eiiect-as thestripper yields to permit the tools to project therethrough and cut thevamp. "In Fig. 11 is shown a somewhat difi'erent style of die.

In the style of punching machine herein shown, the support for the vampis fixed on the bed 53 of the press by means of bolts 54, Fig. 2, and asshown comprises a plate 55 havin an upper surface 56 of materialsuitable or co-operation with the cutting tools without injury to thelatter. The support 55 functions herein both as a vamp esupport and as aplaten and has a reduced extension 57 carrying the vamp gage.

The gage comprises, as illustrated, a pair.

of plates 58 which, in the present instance, are rounded at their frontends and curved rearwardly at the sides where they engage the side edgesof the vamp throat. These plates are designed to fit the throat of av'amp such, for example, as that indicated in broken lines at 59 in Fig.3. They may, however, have any form determined by the style of vamp withwhich they are to be used. The plates are detachably secured, as bymeans of pins 60, to plates 61, respectively, these plates 61 beingadapted to slide longitudinally or toward and from the die, in guidewaysin plates 62. J To guide the plates 61 longitudinally in plates 62 andyet-cause them to move transversely with the latter, there are providedguide slots 63 in the plates 61' engaged by screws 64 secured to theplates 62. To the bottom of each of the latter is fixed a lug 65 havinga reduced upperportion 66 slidably fitting in a slot 67 extendingtransversely of plate 57, the lugsbeing secured to the plates by meansof screws 68. Fixed to,- the center of plate 57 by means of a screw 69,in line with and between the lugs 65, is a stationary lug 70 having atransverse bore71 in which is rotatably carried a spindle 7 2 ormed witha recess to prevent endwise movement of the spindle in the lug. Thespindle is ide for stitching provided towards'its respectieve ends withvits finger-pieces 76, serves to move lugs 65 toward or from each otherin the slots 67 according to the direction in which the spindle isrotated. The lugs, of course, move thaplates 62 secured thereto as wellas the plates 61 and the gage plates 58 in the same manner, toward 'orfrom each other transversely of the'gage, to contract or expand thegage, to fit the difl'erent Vamps.

To accommodate Vamps of different sizes, means is provided for adjustingthe gage plates longitudinally of the vamp comprising, as illustrated, apair of bell crank levers 77 (Figs. 5 and 7 fulcrumed at 78 to the underside of plate 57, each lever having a slotted arm 79 connectedadjustably to the corresponding lug 65 and having also a slotted arm 80engaging a pin 81 depending from the corresponding plate 61. Slots 82are provided in the plates 62 to enable the pins 81 to movelongitudinally when the plates 61 slide in their guideways in plates 62and a pair of circular openings '83 are formed in plate 57 to enable thepins 81 and the plates 61 and 62' to have .both transverse andlongitudinal movement. The slotted arms 79 engage pins 84 rising fromangular blocks 85 screwed to threaded guide pins 87 which slide in guideholes88 in the lugs 65. The position of the pins 84 in the slots of thearms 7 9 determines the, ratio of the longitudinal and transversemovements of the gage plates and this ratio may be changed as desired tosuit the different systems of size measurement or variations in grade.The blocks 85 carrying the pins 84 are forked as indicated at 86, and,extending into these forks, are the slotted ends 94 of a bar 93 whichcan be adjusted by means of a screw rod 89. The screw rod 89 has afinger piece 90 at one end and at the other end is secured rotatably tothe block 70 by a'collar 92. The rod is threaded into the bar 93 so thatrotation of the rod moves the bar and the angular the position of thesepins 84in the slotted arms 79. A look nut- 95 may be used to fix theadjustment. It is evident that as the lugsf65 are adjusted outwardly,the plates 62 and 61 will be carried transversely, the reduced portions66 of the lugs 65 movingin the slots 67 of the plate. 57Simultan'eously, the angular blocks 85 and pins 84 are carriedtransversely and rotate the bell crank levers 77 on their pivots.results in a longitudinal. movement of the pins 81 in the slots 82 andcauses the plates 61 to slide longitudinally in the guideways of theplates 62. The ratio of blocks 85 to vary This justment forvamps of the.usual seriesof' sizes.

The operation of the device requires but a brief explanation inconnection with the' description of "its construction. The rotatlon ofspindle 72 is operative, through lugs I 65, to adjust the two gagemembers 58 in opposite directions transversely of the machine, and themotion of lugs is transmitted by levers 77 and pins 81'to move the twogage members 58 longitudinally both in the longitu same direction, thelongitudinal and transverse adjustment beingin a predetermined ratio toaccommodate and correctly to posi- 7 tion different sizes of vamps. Thegage hav- 7 ing been adjusted for the size of the vamp to be operatedupon, the die may be shifted slightly on the die block as described,accordingly as the vamp is a right or a left, to move the punches whichare to perforate the vam towards its outer edge, rearwardly ally of thelatter, and the tools on the other edge in the opposite direction whereit is desired to angle the perfprating to provide a compensation for thedlfierence in adjustment of right and left vamps to the shoe, as wellunderstood in the art.

The press is then operated 'in the manner, usual with machines of thisgtype,causing the die to descend and perforate the vamp, the markingprojections of the stripper plate, if such are used, scoring the. vampto indicate the pro r lines for stitching, where the latter is to E: eployed.

The machine is s mph and eflicient in construction, being adapted for aplication economically to usual forms of punc presses and is especiallyadvantageous in that'it may combine in one machine for simultaneousoperatlon, mechanism for grading or sltioning the'vamp, markin thelatter, and
